SASI-I-LOGK.

To all whom it may concern:

Be it known that we, WALTER S. AnAMs and Gnoneu B. Koi-rnnn, citizens ofthe United States, residing in Philadelphia, Pennsylvania, have inventedcertain Improvements in Sash-Locks, of which the following is aspecification.

The object of our invention is to make a simple and substantial lock orbolt for holding the sash of a car window.

A further object of the invention is to construct the device so that ahorizontal spring bolt can be used in connection with a sash lift, whichenables the bolt to be first withdrawn and the sash raised.

In the accompanying drawings z Figure 1, is a perspective view of ourimproved sash lock; Fig. 2, is a side view; Fig. 3, is a rear view; andFig. 4, is a transverse sectional view on. the line 4-4, Fig. 2.

A is the plate which is secured to the sash in any suitable manner, andB is the bolt which is projected from one end of the plate and enters a.socket in the window frame. This bolt is mounted in a bearing a at theforward end of the plate A and this bearing has a projection a whichpasses through a slot in the sash so that the bolt is supported. at theextreme end of the sash, making it impossible to bend the bolt in theeffort to lift the sash from the outside. The bolt also passes throughopenings in two lugs c, 0 projecting from the back of the plate A andbetween one of the lugs 0 and a shoulder Z) on the bolt B is a spring E,which tends to project the bolt out as this is the normal position ofthe bolt in this class of locks.

Secured to the bolt B is. an arm D which projects through the inclinedslot 7 in the enlarged portion A of the plate A. The outer end of thisarm D is enlarged to form a thumb-hold. Projecting from the portion A isthe sash lift a which is engaged by the fore finger of the hand inlifting the sash.

Specification of Letters Patent.

Application filed November 12, 1910.

Serial No. 591,992.

hen the arm D is moved down it travels on the inclined casing as a camto withdraw the bolt against the pressure of the spring so that when thebolt is withdrawn the sash can be raised without removing the hand fromthe bolt structure. As soon as the arm D is released from the control ofthe thumb, the spring projects the bolt and as the sash is moved up ordown the bolt will travel on the face of the slideway in the frame untilit is projected into a. socket.

Thus it will be seen by the above construction that we make a verysimple and substantial sash lock, which is combined with a sash lift sothat the bolt can be withdrawn and the sash raised by the same hand. Onthe opposite side of the sash there may be simply a plain sash lift orrail which is applied to large windows, or there may be a combined boltand sash lift at each side of the sash.

We claim:

In a. combined sash lift and bolt, the combination of a. flat platehaving a lip projecting from the face thereof and forming the sash lift;a curved projection above the lift integral with the plate and having adiagonal slot therein; bearings at the back of the plate; a longitudinalbolt adapted to the bearings; an arm secured to the bolt and extendingthrough the diagonal slot in the curved projection; the arm beingenlarged at its outer end above the sash lift to form a thumb hold; anda spring encircling the bolt and bearing against a shoulder on the boltand one of the bearings, whereby the bolt is projected when the arm isreleased.

In testimony whereof, we have signed our names to this specification, inthe presence of two subscribing witnesses.
